I could not resist this one, just a little innocent joke! By the way, I did have a Prius, for a while, I sold it! I just don't see the point about removing a pollution device if you don't have too! On a modern fuel injected engine the improvement in power is ridiculously small. On a carbureted motor it's a different story and by all means remove the cats if your local legislation will allow you to do so, the car will run much better. Anyway, I am going back to the other side!
PS I got to find a Pantera thread, this should be a lot of fun![
